[cai-asia] RE: EU next step to improve air quality
Ewa Kalend
Dear Joann Pottberg,
Thank you for information you shared with me, particularly that this topis is quite new and information on new available PM2,5 monitoring technologies are very useful. According to official information, currently in Poland we have only 2 automatic stations for PM2,5 measurement. The new directive on PM2,5 (CAFE) will cause necessity to install several dozen of PM2,5 monitoring systems in coming years (generally it is said about 150 measuring points, but probably part of them will be manual).
By this occasion, I would like to aks about PM2,5 monitoring techniques. According to our knowledge generally in the world there are 2 available basic PM2,5 monitoring techniques: TEOM (Tapered Element Oscillating Microbalance) and BAM (Beta Attenuation Monitor). We are very interested be guide to more detailed information on TEOM, BAM and other techniques as well as to know about objective conclusions of comparision of these techniques and practical remarks resulted from usage experience. I will be very grateful for any responses in that issue.
Kind regards,

to improve air quality
Dear Members of CAI-Asia,
I am writting to share with you information from EU about new regulation that aims to limit the amount of PM 2,5.
Hope you will find it interesting.
EU next step to improve air quality
European governments on April 14th adopted a new directive that aims to limit the amount of particles in the air that can cause a range of health problems, which contribute to the premature death of 350,000 Europeans annually.
The new directive is one of the key measures under the Tematic Strategy on air pollution, adopted by the Commission in 2005. The new regulations require the 27 members of the EU by 2020 to reduce urban air pollution by 20 percent on levels recorded in 2010. This figure is a target value to be attained by January 2010, but will become a binding cap from 2015.
Under the new directive on air quality, the limit on PM 2,5 concentrations is 25 ug/m3 on the average concentration of dust particles with a diameter of less than 2.5 micrometres.Such particles are emitted by a wide range of sources including diesel vehicles, industrial facilities and residential fire places.

The new directive does not change the air quality standards that already exist in Europe, but in our opinion causes some AIRQUALITY/IPPC problems for industry sector. Steel industry has already seen the problem what is expressed by EUROFER (European Confederation of Iron and Steel Industries) standpoint, which indicates that „currently there are no specific abatement techniques for PM 2.5 applicable in the steel industry. The existing dedusting systems’ efficiency for PM 2.5 is limited. Neither electrostatic filters, bag filters, nor scrubbers are suitable for such a task.” The other European industry sectors do not express them`s concerns in such a straight way, however the problem can also apply for them (i.e. cement industry). The other problem is that in Europe there are no standards for PM 10 and PM 2,5 measurement.
Please let me know about your point of view in that issue.
With best regards,

Your earlier e-mail about the EU's new PM2.5 standard mentions the limit as 25 microg/m3. Is that a 24-h limit (i.e. the PM2.5 mass should not exceed 25 microg/m3 during a 24-h period) or an annual average? For instance, the US EPA says the annual PM2.5 cannot exceed 15 microg/m3, while daily 24-h concentrations can go as high as 35 microg/m3.
You also talked about the regulations affecting industry. It looks like the regulation is similar to the US NAAQS - ambient conditions. So to regulate emissions from sources, you need to know how much these industries contribute to the ambient PM2.5. Presumably you already do this for PM10, either through source apportionment of ambient measurements and/or an emissions inventory.
Finally, I was involved in a study looking at PM2.5 in Pittsburgh, Pennsylvania, USA. One of my colleagues, Sarah Rees, looked at PM2.5 mass concentrations, intercomparisons between the EPA's Federal Reference Method (an integrated filter-based approach) and the TEOM, and PM2.5 mass composition. The intercomparison should be objective - we did not make any of these instruments! I will send that paper to you separately (not sure what the journal's copyright restrictions are if I post it to the list). For the other folks on this list, the reference is:
Rees, SL et al. (2004). "Mass balance closure and the Federal Reference Method for PM2.5 in Pittsburgh, Pennsylvania." Atmospheric Environment, vol 38: 3305–3318.
Of course, if anybody wants a copy and is unable to get it elsewhere, you can ask me. Also, my personal website below has a description of my involvement in that project.
Hope that is helpful,
Subramanian
